Trying to execute a Beetle boards “AT+…” commands from “BlunoBasic Demo” android App

I can apparently get the Beetle into the “AT” mode by sending “+++”, but I cannot get an “AT” command to execute, apparently because I cannot put the required new-line & carriage-return codes at the end of the “AT” command.
Can the new-line & carriage-return codes be input from the keyboard that comes up with “BlunoBasic Demo”? If so how?
Is there another way?

It would be nice if the “BlunoBasic Demo” had a user button that could switch between sending a new-line & carriage-return on the end when the “send” button is pushed; and the current “send” method.
Thank You!
